Well there's no IP on usb0.
ifconfig usb0 192.168.0.202 netmask 255.255.255.0 up
should help with that.
If this is with a kernel with the Ethernet gadget built as a module, I
wonder if there's a race somewhere between inserting the module and
trying to bring up the interface in initscripts.

This is reminding me of a problem we have with level interrupts on pcf50633 new driver, we also get twice the same interrupt there although the density of interrupts is so low and logically it cannot get confused so it doesn't make trouble. We also changed lis302dl to use level interrupts so it's suspicious now we see this behaviour that is so similar. -Andy Thanks, Is somebody working on this or should I write a bug report?

Also check the threshold file afterward you've set it so that it's not zero, values which are too low to be represented by the threshold code get rounded down. HI, I made a mistake. I do not really get two different values I get twice the same (3D) value but a different timestamp (see below). But anyway this is not correct. I don't want to set a threshold, because I need every value with an equidistant timestamp. Any idea what's going wrong? Do you have this test program to share? I send U the binary of my C++ Acc Test tool offlist. If somebody else wants it I can send it. I attached the source code. You should use it with 2.6.28 Kernel otherwise U must set threshold and sample_rate manually because it is in a different folder. you will need to install one additional lib: opkg install libgio-2.0-0 It's a simple terminal tool use it the following way: MokoAcc [Number of Loops] [Accelerometer 1 or 2] [100 or 400 (Hz)] [threshold] for example: ./MokoAcc 10 2 100 0 and it will create a log file in the same directory: cat AccLog_Acc1.txt 455.131012 -0.528137 0.704183 5.633463 455.322998 -0.528137 0.704183 5.633463 457.576996 -0.176046 0.704183 8.978332 457.766998 -0.176046 0.704183 8.978332 460.061005 -0.352091 0.704183 8.626241 460.411987 -0.352091 0.704183 8.626241 462.503998 -0.352091 0.880229 8.626241 462.700012 -0.352091 0.880229 8.626241 484.566010 -0.352091 0.704183 8.626241 484.790009 -0.352091 0.704183 8.626241 first value is the timestamp in ms the X,Y,Z; Greets Michael AccTest.tar.gz Description: application/compressed-tar ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
